RPM Innovations (RPMI) designs and builds high-performance laser deposition systems used worldwide for Directed Energy Deposition (DED) manufacturing. With thousands of production hours behind every machine design, RPMI systems offer unmatched reliability for building, repairing, and enhancing high-value metal components.
Whether you’re creating large freeform structures or restoring critical parts to like-new condition, RPMI systems deliver the accuracy, repeatability, and strength you need.
Proven production experience
Each system is engineered from real industrial use, ensuring dependable performance in demanding manufacturing environments.
Versatile build volumes
From compact units to large-format systems capable of handling parts up to 5 feet by 5 feet by 7 feet, RPMI supports everything from R&D to full-scale production.
Wide material selection
Advanced multi-axis capability allows complex geometries, multi-directional deposition, and highly controlled metal builds.
Controlled inert atmosphere
Hermetically sealed chambers with inert gas environments protect the melt pool, improve deposition quality, and minimize contamination.
High-power fiber lasers
Systems support multi-kilowatt fiber lasers for strong, efficient metal deposition with excellent surface integrity.
Dual powder feeders
Servo-controlled powder delivery ensures stable feed rates, continuous operation, and the ability to blend or switch materials.
557XR Laser Deposition System
